This example uses the Iris dataset to render a 3D scatter plot, mapping petal length, sepal length, and petal width onto the x, y, and z axes. Each data point is colored individually to show distribution across the three dimensions. The visualization is built with Highcharts’ `scatter3d` chart type, loading data via D3’s `d3.csv` parser. Interactive rotation is enabled through custom mouse and touch event handlers that adjust the chart’s `options3d` alpha and beta angles. The plot includes axis limits, grid lines, and a legend, with radial gradients applied to the points for depth perception.
